Sam broke free of his leash and went after a miniature pinscher. The dog's owner owner shot Sam.

"I'm not excusing what happened on my behalf or my dog's behalf, but I think guns are a very last resort and once you pull that trigger you can never undo," Warner said. "It blows my mind that people carry guns to walk their dog in a residential neighborhood."

Ricky Powell, the owner of the mini pinscher, said he tried getting his dog out of the pit bull's mouth, but couldn't.

"That's the only time I've ever pulled it and I hope it's the last time I pull it but in this case if I didn't pull it, my dog would be dead," said Powell.

Powell called 911 from the scene.

"My dog was just attacked by a pit bull and I shot the dog," Powell said on the call.

A DeBARY MAN SAYS HE HAD NO CHOICE BUT TO SHOOT A PIT BULL ATTACKING HIS DOG. THE MAN SAYS HE WAS WALKING HIS PINCHER WHEN THE PIT BULL GOT LOOSE FROM THE LEASH. CLAIRE METZ JOINS US LIVE IN DA BARE WRI WHERE THE ATTACK HAPPENED LAST NIGHT. CLAIRE? TELL YOU WHAT, BRETT, THE PIT BULL'S OWNER IS FROM NEW YORK, WAS IT VISITING WITH AN ELDERLY AUNT HERE ACROSS THE STREET WHEN HER PIT BULL BROKE FREE OF THE LEASH THAT WAS TIED TO THE TREE. SHE SAYS SHE UNDERSTANDS SOMEONE TRYING TO PROTECT THEIR PET BUT SHE THINKS THE DeBARY MAN WENT TOO FAR. HE HOWEVER SAYS HE HAD NO OTHER CHOICE. IT BLOWS MY MIND THAT PEOPLE CARRY GUNS TO WALK THEIR DOG IN A RESIDENTIAL NEIGHBORHOOD. ANN WARNER IS HEADING HOME HEART SICK BECAUSE HER DOG OF TEN YEARS, A PIT BULL RESCUE NAMED SAM, DIED ON THE OPERATING TABLE AFTER BEING SHOT ACROSS THE STREET FROM HER AUNT'S HOME. SAM BROKE FREE OF HIS LEASH. WE HAVE PICTURES FROM ANIMAL CONTROL AND WENT AFTER THIS MINI-PINCHER. YOU CAN SEE THE BITE MARKS. BUT WARNER THINKS THE OWNER OVERREACTED. I AM NOT EXCUSING WHAT HAPPENED ON MY WA BEHALF OR MY DOG'S BEHALF. BUT I THINK GUNS ARE THE VERY LAST RESORT. AND ONCE YOU PULL THAT TRIGGER YOU CAN NEVER UNDO. WE WENT TO RICKY POWELL'S HOME, THE OWNER OF THE MINI-PINCHER, BUT THERE WAS NO ANSWER. HOWEVER, POWELL CALLED 911 FROM THE SCENE. MY DOG WAS JUST ATTACKED BY A PIT BULL AND I SHOT THE DOG. HE EXPLAINED HE CROSSED THE STREET BECAUSE IT WAS BARKING AND JUMPING. THEN SAYS THE PIT BULL SUDDENLY GOT LOOSE AND CHARGED HIS PET. IT ATTACKED MY DOG AND I TRIED TO PULL IT THREE OR FOUR TIMES AND I COULDN'T KEEP IT AWAY. IT HAD ITS MOUTH AROUND IT AND I SHOT IT. POWELL HAS A CONCEALED WEAPONS PERMIT AND BY FLORIDA STATUTE PEOPLE HAVE THE RIGHT TO PROTECT DOMESTIC ANIMALS OR LIVESTOCK. I HAVE A RIGHT TO PROTECT MY DOG. I UNDERSTAND SIR. BUT WARNER WHO SAYS SHE IMMEDIATELY RAN OUTSIDE IS CERTAIN THE DOGS COULD HAVE BEEN SEPARATED BY SOMETHING OTHER THAN DEADLY FORCE. I FEEL LIKE THAT SHOULD NEVER BE THE FIRST SOLUTION. I THINK WHEN PEOPLE HAVE GUNS, I DON'T THINK THEY LOOK FOR OTHER RESOLUTION. BACK LIVE NOW. REALLY SAD ALL AROUND. IN THE LAST HOUR WE SPOKE ON CAMERA WITH MR. POWELL. COMING UP AT SIX, YOU WILL HEAR WHAT HE HAS TO SAY ABOUT ALL OF THIS. HIS PERSPECTIVE. HIS DOG HAD TO BE TREATED AT THE HOSPITAL FOR HER LACERATIONS AS WELL.
